Recommended Usage

PLEASE OBSERVE THE FOLLOWING TO REDUCE THE RISK OF INJURY:

Installing the Shower

1. Installation of the shower must be carried out in accordance with these

instructions by qualied, competent personnel. Read all instructions before

installing the shower.

2. DO NOT install the shower where it may be exposed to freezing conditions.

Ensure that any pipework that could become frozen is properly insulated.

3. DO NOT perform any unspecied modications to the shower or its accessories.

When servicing only use genuine Kohler Mira replacement parts.

4. If the shower is dismantled during installation or servicing then, upon completion,

an inspection must be made to ensure all connections are tight and that there

are no leaks.

Safety Information

WARNING ! This shower can deliver scalding temperatures. For continued

safe operation, follow all instructions, warnings and cautions contained

in this guide and on or inside the shower. Periodic maintenance may be

required to keep the product in good working order.

The function of a thermostatic mixing valve is to deliver water consistently

at a safe temperature. In keeping with every other mechanism, it cannot

be considered as functionally infallible and as such, cannot totally

replace a supervisor’s vigilance where that is necessary. Provided it is

installed, commissioned, operated and maintained within manufacturers

recommendations, the risk of failure, if not eliminated, is reduced to the

minimum achievable.

1393515-W2-A

Using the Shower

5. The shower must be operated and maintained in accordance with the

requirements of this guide. Make sure you fully understand how to operate

the shower before use, read all instructions and retain this guide for future

unit or ttings is frozen.

7. The shower can be used by children aged from 8 years and above and persons

with reduced physical, sensory or mental capabilities or lack of experience and

knowledge if they have been given supervision or instruction concerning use

of the appliance in a safe way and understand the hazards involved. Children

must not be allowed to play with the shower.

8. Anyone who may have diculty understanding or operating the controls of any

shower should be attended whilst showering. Particular consideration should

be given to the young, the elderly, the inrm or anyone inexperienced in the

correct operation of the controls.

9. DO NOT allow children to clean or perform any user maintenance to the shower

unit without supervision.

10. Always check the water temperature is safe before entering the shower.

11. DO NOT adjust the temperature control rapidly while using the shower.

12. Use caution when altering the water temperature while in use, always check

the temperature before continuing to shower.

13. DO NOT switch the shower o and back on while standing in the water ow.

14. DO NOT t any form of outlet ow control. Only Mira recommended outlet ttings

should be used.

15. The showerhead must be descaled regularly. Any blockage of the showerhead

or hose may aect showering performance.

16. The water supplies to this product must be isolated if the product is not to be

used for a long period of time. If the product or pipework is at risk of freezing

during this period they should also be drained of water.

Installation

General

1. Installation of the shower must be carried out in accordance with these

instructions by qualied, competent personnel.

2. The plumbing installation must comply with all national or local water regulations

and all relevant building regulations, or any particular regulation or practice

specied by the local water supply company.

3. Make sure all pressures and temperatures comply with the requirements of the

shower. See ‘Specications’. For Type 2 Valves, refer to supply conditions

given in the TMV2 Requirements Manual (this is available to view or

download from our website www.mirashowers.co.uk).

4. Full bore/non restrictive servicing valves must be tted in a readily accessible

position adjacent to the shower to facilitate maintenance of the shower.

DO NOT use a valve with a loose washer plate (jumper) as this can lead to a

build up of static pressure.

5. DO NOT apply excessive force to plumbing connections; always provide

mechanical support when making plumbing connections. Any soldered joints

should be made before connecting the shower.

6. Pipework dead-legs should be kept to a minimum.

7. DO NOT install the shower unit in a position where access for maintenance is

restricted.

8. The shower must be tted to a waterproof, at and even wall surface. The

two screws and wall plugs supplied are suitable for most solid wall installations.

Alternative xing screws for panel structures are not supplied. Use both xing

points to secure the shower, be sure to use xings appropriate for the chosen

wall structure.

9. When pipework enters the product from the rear through a hole in the wall,

provision must be made to prevent water ingress back into the wall structure.

10. Position the shower unit where the controls are at a convenient height for the

user. Position the showerhead so that the water sprays in line with the bath or

across the opening of a shower cubicle. The installation must not cause the

shower hose to be kinked during normal use.

Suitable Plumbing Installations

The Thermostatic Mixer can be installed with all systems with balanced pressures.

Mixed gravity and mains supplies are not recommended.

1393515-W2-A

11. The water supplies to this product should be isolated if the product is not to be

used for a long period of time. If the product or pipework is at risk of freezing

during this period they should also be drained of water.

12. The position of the shower and shower ttings must provide a minimum air

gap of 25 mm between the showerhead and the spill over level of any bath,

shower tray or basin. There must be a minimum distance of 30 mm between

the showerhead and the spill over lever of any toilet, bidet or other appliance

with a Fluid Category 5 backow risk.

Note : There will be occasions when the hose retaining ring will not provide a suitable

solution for Fluid Category 3 installations. In these instances an outlet double

checkvalve must be tted, this will increase the required supply pressure typically

by 10 kPa (0.1 bar). Double checkvalves tted in the inlet supply to the appliance

cause a pressure build up, which aects the maximum static inlet pressure for the

appliance and must not be tted. For Fluid Category 5, double checkvalves are

not suitable.

Commissioning

Maximum Temperature Setting

Before using the shower, the maximum temperature must be checked to make sure

that it is at a safe level. It has been preset to a safe showering temperature under

ideal conditions at the factory, appropriate for most systems. However, site conditions

and personal preference may make it necessary to reset this temperature.

1. Turn the temperature handle anticlockwise until it stops and test that the

temperature of the water from the shower outlet is hot enough.

2. If not, depress the override button and carefully rotate the handle further. If the

water temperature is still not hot enough complete the following procedure.

3. Rotate the temperature selector handle back to the override position.

4. Remove temperature handle by pressing the override button and pulling the

handle.

Note: Make sure that the hot water temperature is at least 55°C and that

there is sucient supply.

Caution! Before testing the mixer, make sure that the hot and cold water

is owing correctly by exercising the temperature handle from hot to cold.

Install the shower ttings, refer

to the Installation Guide packed

with the product.

On some models (Assist and React) a 6 l/min

ow regulator can be tted into the outlet.

Cleaning

Many household and commercial cleaners, including hand and surface cleaning

wipes contain abrasives and chemical substances that can damage plastics, plating

and printing and should not be used. These nishes should be cleaned with a mild

washing up detergent or soap solution, and then wiped dry using a soft cloth.

Important! The showerhead must be de scaled regularly, keeping the showerhead

clean and free from lime scale will ensure that your shower and showerhead continue

to perform to their maximum. A blocked showerhead can restrict the ow rate and

may cause damage to your shower.

Cleaning

deliver a constant hot water inlet supply.

Check the shower handset, hose and inlet lters for any blockage and

clean where necessary.

Fluctuating or reduced

ow

Check the shower handset, hose and lters for any blockage.

Make sure that the maintained inlet pressures are nominally balanced

and sucient. Refer to Specications.

Air lock or partial blockage in the pipework.

Water leaking from

the shower handset/

overhead

Normal for a short period after shut o.

Check that the pressures are not in excess of the specications for this

product.

There may be occasions where the overhead shower or shower handset

empties for a while after the shower has been used, this is due to changes

in ambient temperatures and is normal. It is recommended that all outlets

are therefore enclosed within the water catchment area.
